SPECIFICATION forming part of Letters Patent No. 500,682, dated July 4,1893.

Application filed March 29, 1898- Serlal No. 468,161. (No model.)

To all whom it may concern:

Be it known that we, LoUIs ALBERT J ULES VALLJ'IE and ADOLPHE LoUIsGUILLAUME apparatus.

SCHULTZ, of the'city of Paris, France, have invented certain new anduseful Improve ments in Apparatus for Molding the Heads of Dolls, ofwhich the following. is a full, clear, and exact description. p

This invention relates to molding the heads of dolls from a tube of anysuitable material, preferably celluloid, by means of an expanding andcontracting die and matrix.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which Figure 1 represents a section of the entireFigs. 2 and 3 are sectional elevations of the die and mold in twopositions, the face halves of the die and matrix being removed Fig. 4 isa section of the matrix, the die beingin elevation and the partsseparated as in the operation of removing the molded article. Fig. 5 isa horizontal section, on line 12 Fig. 2, of the lateral segments of thedie.

The matrix is made in halves a b hinged together at d and provided withhandles 0, the internal configuration of the halves a b of the matrixcorresponding respectively to the face and back of the head to bemolded. The die is composed of a face portion e, a back portion f andtwo side portions Z m in- -termediate of the face and back portions e f.

The parts e fare hinged together at g, their inner faces being separableto an extent limited bya lug h fixed in the one part engaging in theother part, as shown in Fig. 1. They are provided with extensions 1'having apertures j to receive a locking pin 76. I

The intermediate portion of the die which constitutes the main featureof the invention is made in two partsl m corresponding in configurationto the sides of the head, the two parts being hinged together by a pin02. in a plane perpendicular to the plane of the hingepin h so thatthese parts are expansible laterally while they are wedge shaped bytheir front and rear faces being inclined toward each other so as to fitinto the wedge-shaped space between the inner faces of the front andrear parts e f of the die. The lateral expansion of the parts Zm iseffected by a wedgeshaped key 10 whose edges are received in grooves oin theinner faces of the parts Z m, the wedge p being attached by ashank q to a handle and being provided on each face with studs 1"engaging in slots 8 in the parts Z m, so that by forcing the key 1)inward the intermediate members of the die are expanded laterally, as inFig. 2, and by withdrawing it they are contracted, as in Fig. 3. Thewedge has an aperture 25 for the locking pin It.

The operation of moldihg celluloid is as follows: The several parts ofthe die havingbeen fitted together and secured in the expanded positionby means of the locking-pin It, the

the suitable diameter and length to form the head of the doll, it beingessential, in order that the molding may be properly performed, that thedie should not enter the tube too easily. The die, incased in celluloid,is then dipped for about one minute in boiling water, in order to softenthe material, after which it is placed in the matrix a b, the lockingpink is withdrawn and the two parts abof the matrix closed together bythe handles a and while so held the mold is again plunged in hot waterfor a few minutes and then suddenly dipped in cold water in order toharden and contract the molded material so that it may be readilydetached from the matrix. The key 19 is then withdrawn therebycontracting the two parts I m laterally'as shown in Fig. 3 so as toenable them to be detached and withdrawn from the molded article. Theremoval of the wedge shaped intermediate portion Zm of the die allows ofthe face and back parts e f being brought together by means ofthehandles 2' andso disengaged in turn and removed from within themolded article. The matrix is then opened and the molded articleremoved. It will be understood that any other suitable material may besimilarly molded.

We claim- 1. The herein described apparatus for molding the heads ofdolls in a single piece from a a wedge or key inserted between thelateral parts and adapted to force them outward laterally, substantiallyas specified.

2. In the herein described apparatus the combination with a two parthinged matrix, of afour part die constructed of face and back partshinged together, wedge shaped intermediate lateral parts hinged togetherat right angles to the front and back parts, and a wedge shaped keyfitting in grooves between the lateral parts, and engaging, by studs andslots, with said parts so as, by itsinsertion, to

expand and by its withdrawal to contract said intermediate lateral partsof the die, substantially as specified.

The foregoing specification of our improved apparatus for molding theheads of dolls signed by us this 14th day of March, 1893.
